U-Tube Heat Exchanger Manufacturer in Chennai & India

KRR is a premier U-tube heat exchanger manufacturer in Chennai, supplying exchangers engineered for thermal flexibility, cyclic operation and long service life.

In a U-tube design, each tube is bent into a U-shape, allowing it to expand and contract freely without imposing stress on the tube sheet. This eliminates differential expansion loads and makes U-tube exchangers ideal for high-temperature, high-pressure and rapidly fluctuating process conditions.

KRR manufactures U-tube exchangers using:

  • Carbon steel

  • Stainless steel

  • Duplex & super duplex

  • Titanium and nickel alloys

Why U-Tube Design

  • No thermal expansion stress

  • Thinner tube sheets

  • Lower fabrication and lifecycle cost

  • Exceptional reliability in cyclic duty

Used extensively in refineries, chemical plants, power stations and heat recovery systems.
